Warden is a new hostile mob with interesting features, that make gameplay around him unique. For starters, he is completely blind but has a very good hearing, which makes him react to every sound. If he will find out that you're wandering somewhere close by - he is probably going to kill you. However, there is a way to avoid death by Sneaking by past him. Warden is a fun new mob that is going to change the way we play Minecraft PE, and the addon allows you to test it right now.
